Please give me an idea, why you think programming the eprom via serial should not be possible. The parameter of the Z-Stick Gen5 are in the database like for e. g. the multi sensor 6, also Aeon Labs. And in Habmin I see many configuration parameters for the multi sensor. Also in Paper UI I see the possibility to deactive/activate security network mode, which seems equal to setting parameter number 242.
As I said, in my discussions with Sigma they said that the serial API that they provide, which is the basis for all zwave controllers, doesn’t support this. Now maybe Aeon have implemented support for this, but I also read somewhere else on the net (in the OZW forum I think) that it was also only possible to do this from another controller and not via serial so this would be consistent.
Yes - this is what I said above - for normal devices configuration is available through HABmin or PaperUI. Sorry if I don’t understand your point here.
